b) male (18+ years): 59 - 103 mcmol/l or 0.67 - 1.17 mg/dl * has history of a malignant disease other than properly treated carcinoma in situ of the cervix or basal cell or squamous cell carcinoma of the skin within 24 months prior to icf signature * has history of pharmacoresistant epilepsy or multiple episodes of migraine (defined as at least 1 episode within 6 months of icf signature) not completely controlled by medication * participants must not be receiving steroids (oral or parenteral daily dose of \>= 0.15 milligram per kilogram per day (mg/kg/day) of prednisone or equivalent) or other immunosuppressive drugs or chemotherapy * females who are pregnant, breast feeding or planning a pregnancy during the course of the study. women who become pregnant during the study will be withdrawn from the study * has participated in another clinical study within 3 weeks prior to study icf signature * has history of drug or alcohol abuse within the 6 months before screening * has employed or a direct relative of an employee of the cro, the study site, or the sponsor * previously treated under this protocol * unable to provide informed consent or provide informed consent by a legally authorized representative
